[RESOLVED] DataGridViews & checkboxes

Hi,

I have a datagridview and in it a column of checkboxes. How can I get it to where IF ANY of the checkboxes in that column are clicked on (event change), then a MessageBox will show up...

Thanks for the help!!!

I have something like:

Code:

---

Private Sub dgvWeldingLog_CellContentClick(ByVal sender As System.Object, ByVal e As System.Windows.Forms.DataGridViewCellEventArgs) Handles dgvWeldingLog.CellContentClick

        MessageBox.Show("hello", "world", MessageBoxButtons.OK, MessageBoxIcon)

End Sub

This works, but it works for ALLL the columns. I only want it to do it for the column with the checkbox in it.

If you look in your event signature you will see the variable 'e'. If you access the members of said variable you will see some properties that will help you.

Replace YourColName with the column name to work with. I do not check to see the type of column as I am sure the name is correct in regards to YourColName is a CheckBox column type.

Code:

---

Private Sub DataGridView1_CellValueChanged( _
        ByVal sender As Object, _
        ByVal e As System.Windows.Forms.DataGridViewCellEventArgs) _
        Handles DataGridView1.CellValueChanged
       
    If DataGridView1.CurrentRow IsNot Nothing Then
        If e.ColumnIndex = DataGridView1.Columns("YourColName").Index Then
            If CBool(DataGridView1.Rows(DataGridView1.CurrentRow.Index).Cells("YourColName").Value) Then
                MsgBox("Checked")
            Else
                MsgBox("UnChecked")
            End If
        End If
    End If
   
End Sub

Private Sub DataGridView1_CellContentClick( _
        ByVal sender As Object, _
        ByVal e As System.Windows.Forms.DataGridViewCellEventArgs) _
        Handles DataGridView1.CellContentClick
       
    If DataGridView1.CurrentRow IsNot Nothing Then
        If e.ColumnIndex = DataGridView1.Columns("YourColName").Index Then
            If CBool(DataGridView1.Rows(DataGridView1.CurrentRow.Index).Cells("YourColName").Value) Then
                MsgBox("YourColName")
            Else
                MsgBox("UnChecked")
            End If
        End If
    End If
End Sub

Also here is a demo I did with what I call dualling checkbox columns

Thanks for the response! I finally figured it out before I even read your post. This seems to work...so far:

Code:

---

Private Sub dgvstuff_CellContentClick(ByVal sender As System.Object, ByVal e As System.Windows.Forms.DataGridViewCellEventArgs) Handles dgvstuff.CellContentClick

        If dgvstuff.CurrentRow.Cells("dgvcheckboxcolumn").Selected = True Then
            MessageBox.Show("hello", "world", MessageBoxButtons.OK, MessageBoxIcon.Hand)
        End If

    End Sub

Great although you should get in the habit to check that there is a current row, maybe there always is in this code but not in another project.

Hey, Thanks for the help! I'm actually running across a minor issue with both of our codes. Whenever I check a checkbox that's empty, it still gives me the message "unchecked" instead of "checked". Actually it NEVER gives me the message "checked".

Here is a working copy where only the first CheckBox column is done with a Msgbox. This attached VS2008 is a slimmed down version of the one I suggested you review in an earlier post.
